How to check the results on Guangzhou ophthalmic checklist
Guangzhou is one of the medical centers in China, with first-class medical facilities and professional medical team. Ophthalmology is one of the important branches, which plays a vital role in people's vision health. In Guangzhou, many people learn about their eye health through eye checklists. This article will introduce in detail how to examine the results of the Guangzhou Eye Examination Checklist to help readers better understand and deal with their eye problems.
Corneal curvature
Corneal curvature refers to the degree of curvature of the cornea, which is one of the key indicators of normal vision. On the ophthalmic checklist in Guangzhou, the corneal curvature is usually represented by K1 and K2, representing the horizontal and vertical curvature respectively. The normal corneal curvature range is between 38 and 50, and above or below this range may cause vision problems.
If the corneal curvature is too high, it may be one of the reasons for myopia. The cornea of myopic patients is too steep, which makes the light unable to focus on the retina accurately, thus causing blurred far vision. If the corneal curvature is too low, it may be one of the reasons for hyperopia. The cornea of hyperopia patients is too flat, resulting in the inability of light to focus on the retina, resulting in blurred near vision.
In addition to the routine corneal curvature test, the results of corneal topography will also be included in the ophthalmic checklist. This will provide more detailed information about the shape of the cornea and help doctors diagnose and treat eye problems more accurately.
Lens assessment
The lens is a transparent structure in the eye, which is responsible for regulating the focusing ability of the eye to objects at different distances. On the Guangzhou Ophthalmology Checklist, lens evaluation usually includes information such as lens measurement value and lens relaxation force.
Lens measurements refer to the thickness and shape of the lens. Normal lens thickness ranges from 3.0 to 5.0. Any abnormality beyond this range may cause vision problems. The relaxation force of the lens refers to the flexibility of the lens in the process of focal length adjustment, which plays an important role in the focusing ability of the eye.
Through the lens evaluation results on the ophthalmic checklist, doctors can judge the functional state of the lens, and then diagnose and treat related eye diseases. For example, sclerotic lenses are a common feature of cataracts, which can lead to blurred vision and reduced sensitivity.
Fundus examination
The fundus is one of the most important parts of the eye. Through the fundus examination results on the ophthalmic checklist, doctors can understand the health of the blood vessels, optic nerve, retina and other structures of the eye.
Fundus examination is usually carried out by means of optoscope or ophthalmoscope, and doctors will observe and evaluate the shape and condition of fundus blood vessels. If the eyeground blood vessels are abnormal, it may mean the existence of hypertension, diabetes and other systemic diseases.
In addition, fundus examination can also find out whether the patient has eye diseases such as retinal detachment and macular degeneration. These diseases may lead to serious vision problems, and early detection and treatment are crucial for patients' vision protection.
Intraocular pressure test
Intraocular pressure refers to the pressure inside the eyeball, which is of great significance to the health of the eye and the risk assessment of glaucoma. On the ophthalmic checklist in Guangzhou, the common intraocular pressure test methods include non-contact tonometer and electronic tonometer.
The normal intraocular pressure range is between 10 and 20 mmHg. Exceeding this range may mean that the patient has increased intraocular pressure. High intraocular pressure may be one of the early symptoms of glaucoma. If not treated in time, it may lead to damage to the optic nerve and permanent loss of vision.
Through the intraocular pressure test results on the ophthalmic checklist, doctors can evaluate the patients' intraocular pressure, so as to judge and deal with the risk of glaucoma.
Summary
The Guangzhou Ophthalmology Checklist provides a wealth of information to help people understand their eye health. By examining the results of corneal curvature, lens assessment, fundus examination and intraocular pressure examination, we can better understand and deal with eye problems.
